[That is easier to answer, and Kratos's head shakes the denial of the assumption before he even considers the route to the question. Well, he's already admitted to being the only angelic human; and general information is better than personal.]

No. There are no pure angels; they can only be made. Remiel is -- was -- a half-elf. He looks the way he does because he never learned proper control of the mana used in creating his wings. Angels like him can't put their wings away, so they're only assigned tasks which need the face of an angel to go with it.
